This invention relatesto-spring structures and beds,

One of the principal objects'of this invention is to provide a spring structure made up of a plurality of individual units. sqconstructed and arranged whereby the same may be readily connected 'oiie w-itlnthe other in fabr ating the sprin structure. l

Another object of ,this :inyention is to provide a spring structure of the above-described character wherein the individualv sprin units are simple inconstruction, durable in use, ,'efi icient in operation, and economical in manufacture.

Other objects and advantages of the invention will be apparent from the following description, appended claims, and annexed drawing.

In the accompanying drawings:

Figure 1 is a perspective view of one of the spring units.

Figure 2 is a side elevation of a spring unit.

Figure 3 is a top plan view of a spring structure illustrating a plurality of the spring units assembled.

Figure 4 is a fragmentary top plan View illustrating a modified form of means for connecting the units together.

Figure 5 is a detail sectional View taken on line 55 of Figure 4.

Figure 6 is a view showing a further modification wherein continuous loops are provided at the corners of the units, the parts being shown in plan.

Referring now to the drawings wherein like reference characters indicate corresponding parts a mattress or cushion structure of this invention includes a plurality of spring units 5 and inasmuch as each of said units is of a like construction, a detailed description of one will sufilce, it being understood that reference numerals of one unit apply to corresponding parts of the other units.

The novel form of spring unit 5 comprises a coil spring provided with straight upper and lower arms 6 and 1 extending from opposite ends of the coil and positioned in spaced horizontal and also vertical planes. One of the arms is positioned on one side of the coil spring and the other on the other, as shown in Figure 1. The arms 5 and l are connected to the end coils of the spring section by arcuate sections 8 and 9 that are tangent to the spring and substantially perpendicular to the arms, being connected to the arms at the corners by rectangular-shaped loops l and II. The opposite ends of the arms are provided with eyes i=2 and 13, and in assembling the unitsthe eyes ofione. spring are positioned-in the lo'ops of adjoining springs.

The arms 6 and I are formed. with V-shaped projections intermediate of the. ends thereof i and on the opposite sides oi the end coils of the spring are open V--shaped loops l tand liwith inwardly -'crimped' sides which are positionedv to. interlock with-the V--..shaped projections I16 and H of the arms tovsecure the units together at: the sides and prevent lengthwise sliding thereof.

In the design shown in Figures 4 and 5-the coil springs are-provided with square loops .18 and l fi 'at-opposite corners thereofand-the. loops of two adjoining springs are secured together by bands 20 that are crimped around the'straight sections thereof as shown in Figure 5.

In the design shown in Figure 6 the square loops are replaced by complete round loops 2i and with the eyes at the ends of the arms of one set of springs engaged in the loops of adjoining springs in the set the springs will be secured together and with the V-shapecl loops engaged with the V-shaped projections at the sides the coil springs will be held in assembled relation as illustrated.

From the foregoing it will be apparent that a simple form of fastening means is provided for coil springs that is especially adapted for use in connection with fabricated spring structures, such as cushion and mattress springs, and wherein said coil springs may be readily assembled without the use of various parts for tying the springs together. The particular construction of the arms of the springs provides means whereby one spring is interlocked with the other and thereby lends to quick and easy assembly of the spring unit.

In assembling the springs the eyes I2 and I3 of one spring are fastened in loops I0 and H respectively of an adjoining spring, and the loops l4 and I5 are snapped over projections lo and H of adjoining loops respectively, as shown in Figure 3. In finishing the opposite end of the structure or spring the loops are turned around so that the eyes 12 and ll! of one loop are fastened in corresponding eyes of an adjoining loop, as shown. For this purpose loops 22 are provided in which the eyes 23 are positioned horizontally instead of vertically, and it will be understood that in some cases the loops and eyes may be twisted or turned through an angle of so that they may be positioned to receive connecting parts of other loops.

It will be understood that other modifications arms integrally connected to the end coils v through arcuate sections with loops at the points of intersection of the arcuate sections and arms, and said arms having projections thereon intermediate of the ends thereof and eyes at the outer ends, said end coils having interlocking elements in the sides opposite: the arms positioned to engage with a projection of an adjoining spring.

2. A coil spring for assembly as a unit in a spring structure and formed with straight upper and lower arms arranged in parallel vertical planes at opposite sides of the axis of said spring, said arms formed with loops at one-end adjacent the respective convolutions and with eyes on the opposite ends thereof for connection with the loop of an adjacent spring whereby to provide straight members throughout the spring structure between the springs and for tying one of said springs to another, said respective convolutions formed with means for connecting said convolutions to the arm of an adjacent spring, and said arms formed between their ends with V -shaped offset portions for interlocking engagement with the connecting means of a convolution of a like adjacent spring.

3. A coil spring for assembly as a unit in a spring structure formed with straight upper and lower arms extended from the last convolutions thereof and positioned in parallel horizontal planes corresponding with the ends of the spring, said arms also positioned in vertical planes at opposite sides of the coil and parallel to the axis of' the; spring, said arms formed with loops at one end through'which the arms are connected to adjacent convolutions of the spring and with eyes on the opposite ends thereof for connection with the loop of the arm of an adjacent spring thereby providing straight members extended throughout't-he spring structure positioned between the springs and through which the springs REFERENCES CITED The following references are of record in the file of this patent:
